Title: Flexible rubber pipes for undersea pipelines - using lead sulphide in rubber to increase density
Inventor: GRUBER KURT DR ING
IPC: F16L11/12
Filed: 1975-10-03
Abstract: Large diameter pipe lines of 300 mm to 500 mm diameter which are laid under the sea to carry oil or gas, are usually made of synthetic rubber reinforced with steel wire. Because of the low density of the material, it is difficult to sink the pipes to the sea bed. This problem is overcome by mixing the rubber with a heavy metal ore such as lead sulphide which is added in a powdered form during manufacture. This method of increasing the rubber density sufficiently to allow the pipes to sink is cheaper than existing methods which use balls of pure lead between layers of vulcanised rubber.

Title: Lead acid accumulator separator - made of microporous resin coated plastic mat with conical dimple impressions
Inventor: MURATA KAZUO
IPC: H01M50/491
Filed: 1975-10-03
Abstract: The separators for a lead-acid accumulator are made of thin carrier layer with large pores to which a solution of a resin, a solvent and a fluid miscible with the solvent has been applied and dried. Dimples are impressed into this foil to contact the positive plates with their points and the negative plates with their flate parts and to act as spacers, filled with electrolyte. This results in separators of high mechanical strength by a partial closure of the micropores. The remaining pores act as filters for heavy metal poisons so that the battery life is lengthened. The separators ensure a high capacity for the accumulator.

Title: Automatic telephone speech identification - uses spectral analysis to identify key features of voice characteristics
Inventor: TIMME MARTIN DIPL PHYS
IPC: G10L19/02
Filed: 1976-10-29
Abstract: An automatic spectral analysis is applied to telephene transmissions to identify the characteristics of normal speech from background noise and cross talk effects. The frequency spectrum for normal speech is in the range 3,00 to 3,400 Hz. A spectral analysis indicates a fundamental frequency (n Vo) and a harmonic (n Vo). In order to identify the speech signal a sample is examined to identify the harmonics, the peak amplitude values and an overall average amplitude value. If two sequential difference values are largely similar and this common value is not smaller than 75Hz or greater than about 350 Hz the maximum can be taken as spectral lines. The fundamental speech sound is classified as a characteristic voiced tone.

Title: Component lubricator control system - uses speed proportional electrical measuring signals transmitted to lubricating gear for lubricant release
Inventor: HERGT OTFRIED ING GRAD
IPC: B23Q1/38
Filed: 1977-04-26
Abstract: The lubrication control system for machines requiring lubrication in relation to the speed of the moving machine part, reduces the lubricant consumption. The control system has a sensor which measures the speed of the moving part in form of nominal value of a controlled driving arrangement. An analogous measureing signal in form of an AC voltage or current with positive or negative polarity is connected to threshold value-less rectifier and after that to a voltage frequency converter. A digital measuring signal, in form of a frequency or pulse sequence frequency is processed by a pulse generating stage. The frequency is fed into a frequency divider consisting of digital counting modules. After a lapse of a preset value the frequency divider produces an output signal switching on the lubricating time stage, which is inversely proportional to the dividing frequency and consequently to the measuring signal, producing a short lubricating interval at high speed and vice versa.
